Allow to pass enablepullrequestautomergeinput.commitBody to the request

[jurijzahn8019]

Hi there!

I woule like to have an input allowing to define commitBody for merge commit.

for example:

uses: alexwilson/[email protected]
with:
  github-token: "${{ secrets.GITHUB_TOKEN }}"
  merge-method: SQUASH
  commit-body: ${{ github.event.pull_request.body }}

or maybe as boolean, taking pr body automatically.

This will allow use case where commit must include contents of PR Body for further
Changelog automations on repos.

Corresponding docs: https://docs.github.com/en/graphql/reference/input-objects#enablepullrequestautomergeinput

Thanks :)
